in the classification of template names and using declarations. We now
properly typo-correct the leading identifiers in statements to types,
templates, values, etc. As an added bonus, this reduces the number of
lookups required for disambiguation.

Fix for PR9633 [indvars] Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.

AddRecExpr in the current scope are folded.

Switch the EmulateInstruction to use the standard RegisterInfo structure
that is defined in the lldb private types intead of passing the reg kind and
reg num everywhere. EmulateInstruction subclasses also need to provide
RegisterInfo structs given a reg kind and reg num. This eliminates the need
for the GetRegisterName() virtual function and allows more complete information
to be passed around in the read/write register callbacks. Subclasses should
always provide RegiterInfo structs with the generic register info filled in as
well as at least one kind of register number in the RegisterInfo.kinds[] array.

from, rather than just blindly adopting the qualifiers of the type
we're converting to or dropping qualifiers altogether. 

As an added bonus, properly diagnose GC qualifier mismatches to
eliminate a crash in the overload resolution failure diagnostics.

an earlier load could be widened to encompass a later load.  For example,
if we see:

  X = load i8* P, align 4
  Y = load i8* (P+3), align 1

and we have a 32-bit native integer type, we can widen the former load
to i32 which then makes the second load redundant.  GVN can't actually
do anything with this load/load relation yet, so this isn't testable, but 
it is the next step to resolving PR6627, and a fairly general class of 
"merge neighboring loads" missed optimizations.

1. Only run the early (in the module pass pipe) instcombine/simplifycfg
   if the "unit at a time" passes they are cleaning up after runs.

2. Move the "clean up after the unroller" pass to the very end of the
   function-level pass pipeline.  Loop unroll uses instsimplify now,
   so it doesn't create a ton of trash.  Moving instcombine later allows
   it to clean up after opportunities are exposed by GVN, DSE, etc.

3. Introduce some phase ordering tests for things that are specifically
   intended to be simplified by the full optimizer as a whole.

This resolves PR2338, and is progress towards PR6627, which will be 
generating code that looks similar to test2.

are probably worse than the old ones, but we now get this right much more
universally, and there's certainly room for improvement in the diagnostics.

This has two effects: 1. We never inflate to a larger register class than what
the sub-target can handle. 2. Completely unconstrained virtual registers get the
largest possible register class.
